I have divided form in to two sections: sec1 and sec2. Each section is part of a div named as sec1Div and sec2Div. Based upon some selection one of div is hidden. But the problem is that still fields in hidden section are submitted. Please suggest a way so that all of fields in a div are not submitted on submit.
There are several ways to do that. You can hook a function to the form submit's event, or you can remove the name attributes of the fields inside the hidden div. You can also disable the fields, by setting disabled="disabled".
If you are using jQuery, you can do those examples.
To disable all fields in the hidden div, you can do something like:
function hideDiv(el) {
$('input', el).each(function(){
$(this).attr('disabled', 'disabled');
});
$(el).hide();
}
And, the appropriate show div function:
function showDiv(el) {
$('input', el).each(function(){
$(this).removeAttr('disabled');
});
$(el).show();
}
Please remind that this is just a code example. But you can take the idea from that.
The reason this is happening is because the elements are still within the form element. Hiding a div using CSS won't change this - they're still present in the DOM.
It would likely be easiest to add a hidden input field to each div that can be used to identify server side which one you should be processing. You can then simply ignore the data from the hidden form.
If you really must stop the data from being posted, it's a little messy but you could move the hidden div's contents outside of the form element so that the fields won't be submitted. If you wanted to display the div again, you'd then need to move the fields back in. Depending on how complex your CSS is, this could cause problems in some browsers, so I'd advise using my first suggestion.

Case:
I have an array of answers which I want to show in the view as radio inputs. When one of the answers is already answered it must be [checked] and if it's [checked] a textarea shows, so far so good.
Next I want to check another radio input and I want the current selected to be deselected and its textarea hidden, then the new selected radio input should be [checked] and it's textarea should show.
I use the FormBuilder and FormArray and have following issues.
I can't use index without intrapolation, I see many examples where the index is used without.
If I select another radio input, first my data disappears and it's not checked and on the second click it get's checked but now both are checked.
- I don't have access to the checked event, I can show it in the view with {{tempVar.checked}} as you can see above, if I use a template variable #tempVar, but I don't have access to it in the textarea below *ngIf="tempVar.checked". If I do use it in the ngIf I get the following error
Expression has changed after it was checked. Previous value: 'false'. Current value: 'true'.
Questions:
Is this the right approach?

Here is my code
https://gist.github.com/webwizart/121c85a0f316f47977cc0c99455af7bf
I would think using the tags should be reserved for unique identifiers? I wouldn't be surprised if dom renderer will update all elements with the same id.
Not sure if this will help, but you could use an answer view model instead (containing the same data) but that also has a 'checked' property
This way you can be sure that it will behave as you would expect.
e.g.: (in your component.ts)
let answers = this.question.Question.PossibleAnswers
.map(a =>
{ return Object.assign({}, a, { checked: false });
}
);
then in html you use: 'answer.checked' instead of 'radio.checked'
ps: also you could use ng-container instead of span, so you don't have an extra DOM imprint in your html
I've tried all the HTL context parameters (even 'unsafe'). When I inspect the input, I can see the value intact, but you can't see the value pre-populated in the field. I tried different types of values, different contexts, and different types of input fields. [AEM 6.2]
<input type="email" name="senderEmail" value="${userProfile.email # context='text'}"/>
If the value is rendered in page source and also visible in browser inspector, could it be that it's hidden by some weird CSS? Something like color:transparent
There are many possible causes. I'll pitch in one, to help get you thinking. Is userProfile available via the use api?
I've made this mistake before:
<div data-sly-use.bean="com.beans.Bean">
${bean.value}
</div>
// ... other code
${bean.value}
The "Bean" isn't available later, outside it's host element.
If I understand your question correctly this isn't actually about HTL, but rather about the HTML input element itself. You have an input element with a value attribute set, yet that value is not displaying in the box. If that's correct, then I'd recommend doing some investigation around HTML input value not displaying when set, rather than sightly context issues.
Some possible answer would include css styles hiding the input text or javascript clearing out the values after page load. There are certainly more potential causes, but we'd need to know more about your page to provide a better answer.
To do some of your investigation you can try loading a component with only that input in it and see if that works, that would eliminate any css or js executing elsewhere on the page.
I have a number of form inputs inside an element as they are repeated in other forms, however it does not output the content of the element when i include it in a view. I can place "Die();" within the element and it will show everything up until that point including the inputs within the element. When checking the source code (without the "Die();") it seems to have disregarded everything within the element including formatting such as DIV's.
The only thing i can think is that cakephp does not like you setting a form in a view then including inputs to the form using elements, does any one know if this is the case, or know the actual reason why this is happening?
The answer is i'm an idiot and forgot to echo the element.... yeah.
I have a question about the wrappers/accordeons. I now have multiple wrappers and in each wrapper there is a form. Now, I want one sendbutton on the end of the page. The sendbutton which will send all the forms that have been filled in at once.
How can I do that?
I don't know why you want to break input into different forms and then submit them again at once. Would it not make sense to use one form and submit the data and process it the way you want using the processFormData hook? may be because you want the accordion to group you form fields. Let me help you this way:
Create your form in the format shown below. Make sure the form has a tabless layout to be able to use fieldsets.
Create a fieldset without a label. You may add the class ce_accordion just in case you have some styling attached to it.
Create a field of type html and add the following markup.
<div class="toggler">Form 1 headline here</div>
Create another field with the following markup
<div class="toggler">
Now create your input fields from here. for example a text field,textares.
Create a field of type html to close html markup created in step 3
</div>
Create a fieldset wrapper end here.
The above steps can be repeated as many as how many groups of fields you want to create in an accordion.
Now create you submit button here and it will send all your data the way you want.
Just a by the way:
If some one submits a form in a wrapper that is closed, how will he know which wrapper has error fields?
$(document).ready(function() {
$(".ce_accordion").each(function(index,el) {
if($(this).find("p.error")){
$(this).addClass("hasErrors");
$(this).find("div.toggler").addClass("active").attr("aria-expanded","true");
}
});
});
You can now add a style for .hasErrors rule
In Drupal 7, is there a way to change the standard edit form for a content type based on a certain content?
For example:
I have a content type with a checkbox...once it it checked and the form is saved, I do not want this checkbox to be visible anymore...therefore based on the checkboxes value in the Database I want to hide form fields when showing the form.
I am building a small specific project site, where a company wants to add projects, and their customers are supposed to follow certain steps (upload some content, provide information etc.), and also should be able to check off certain requirements, and once these are checked off, they should not be visible/editable to them.
Also the displayed form fields should depend on an user's role, and then FURTHER be limited depending on the content's database entries.
Is there a module, which could achieve this behaviour? "rules" and "field/permissions" come close to what I need, but are not sufficient. Or did I just miss the option to change a form field's accessibility based on conditions?
What I need is some place to define a logic like "IF (VALUEOF(CHECKBOX_1) == TRUE) THEN DO_NOT_SHOW(CHECKBOX_1)"
hook_form_alter is the way to do this, as explained by Mihaela, but what options do you have inside that function?
If you want just to disable field (it will be visible, but user can't change it) you can do it like this:
$form['field_myfield']['#disabled'] = TRUE;
And if you want it to be hidden, but to keep value it has before editing the way to do that is:
$form['field_myfield']['#access'] = FALSE;
I.e. hiding it (somewhere I saw someone suggesting that):
hide($form['field_myfield']);
really hides the field, but after that, when form is saved this field has empty value, validation fails, etc, so that's not a good way to do this. Hiding makes sense only if you want to print separately that field later, at some other place.
function your_module_form_alter(&$form, &$form_state, $form_id){
switch($form_id) {
case 'nameOfTheNode_node_form':
//your code here. check the value from from_state.
break;
}
}
In this case, I use module Conditional Fields https://www.drupal.org/project/conditional_fields
For example: If my Dependees field has a value, Dependent field can be visible/invisible, enabled/disabled, required/optional, checked/unchecked
